Be it known that I, 'THEODO'RE W. EviansoLE, a citizen'of the United States, residing at Washington, in the District of Columbla,

have invented 'certain new and useful Im l provements in Self-Heating Soldering Impleto be `a'full, clear, and exact description -the invention,

ments; and I do hereby declare the following o such as will enable others skilled in the art to which it appertains to make and usethe same.. l A

My invention relatesfto that class of selfheating soldering implements'in vwhich vthe fuel to be employed 1s gasolene or a sinnlar volatile fluid supplied from a reservoir which forms the handle of the implement. 4 f` I T@ principal objects ofthe invention are,

'ifirst, to provide for a supply of fuel to the struct the' burner t burner in whatever position the implement may be held or sup orted; second, to so conat an intercha e of solderinltools or points may be rovided for,

and, ird, the ada tation of t. eimplement for use as *a paintreamer Aor as a torch for heating pur oses when used in connection with a suita le heater. These and other objects of the invention are attained by meansl of the mechanism illustratedi'n the accom-l rallying drwi S, in which-f Figure lisa side elevation of m'y improved implement; Fig. 2, a centralV longitudinal section, somewhat enlarged, of the burner and soldering'tool or point; Fig'. 2"', a plan view of y ongitudinalsection, the fuel-reservoir'andthe air-pump;

therein a head projects the g 'outer end of a pumparrel 4. LThe pump- 'barrel near its outer end is provided with a 65 flanged collar .5., and the interior-'of the reservoir is provided with an annular shoulder', a suita le packin `being placed'betweensaid collar and shoul er to provide a fluid-tight connection. 57o

The inner end vof the pumpbarrel is proarranged a spri ressed valve 8, the stem, of which tliro h a screw-threaded,4 :closureplug 9. The va ved'ieadis preferably 7 5 composed-of cork in order 'to better resist the :action of the fluid fuel; but any suitable Amaterial may be employed. The rear end of the extension is provided With a head or plugl,

the puinp-1 8o I provided with an air-delivery .l lport 11,- Said port being normally closed by. the valve 8. The reduced extension is pro-` vided with oppositel -dis osed air-exits 12-A A. 12, and the outer en' of t e pump-barrel -is,8,5 provided withan air-inlet 13; The outer end of the pump-barrel is externally .screw-threaded and isclo'sedby a screw-threaded heador cap 14sad cap be-l -in plrovided with a central borethrough 9o W -c the piston-rod of a piston 15 is adapted'to operate. The outer end of thepiston` rod is 'provide with a knob 16, by meaiisof which the piston lmay be operated.' The head or cap 14 is formed with a semicircular 9 5y boss 17, having a slot 18, andthe piston-rod` carries a in 19,v adapted to enga'gesaid slot, to lock tige piston atthe en d of its inward stroke lwhen desired slight turn. 1 1 j., l o insure-absolute safet ,against'possible leakage of lthe valve 8, which sometimes oc`-, curs whenthe valve is vmade of a material liable to lbecorrf'id'ed lby the gasolene, .'I pre-, fer to make the iston-rod tubular and insert,A x- 9 5 stem 20, as Shown in Fig. 4. In this formfthe outer end off1 the .stem is screw-threaded and works through an open-j' ing' 21 in e kno'bll, said stem-being'also provided V 'a lm ob 22.1 j be obvious;y i xe .barrel and is with a central hub 26, having an internallyscrew-threaded chamber 27, into which' is screwed a uplply-pi e 28, leading to 'the shown in Fig. 7.

burner 29. T e hea 23 is provided at one side with a casing 30, which is in communication with the chamber -27 by means oi a duct 31, controlled by a valve 32. Leading from the inner end of the casing-chamber which opens into the head 23 is a main fuelfeed pipe 33, having a branch 34. The free end of the main feed-pipe extends nearly to the shoulder 6 and has seated loosely therein a valve 35,- whieh is designed to close the main `feed-pipe to the entrance of the fluid 'fuel when the implement is held in a down.- ward position and to open it to the entrance of the lluid when the implement is held in a reverse or upward position, the valve being prevented from dropping out by the shoulder 6, against which it rests when the implement is held in the latter position.

It will be obvious that when the implement is held with its oint in a downward position the ilow of tie liquid fuel will be throu h the branch feed-pipe 34 and thence into t e main feed-pipe, as the entrance to the latter ipe will be closed by the valve 35; butwhent e implement is held with its oint in an upward direction said valve 35 rope down a sufficient distance to allow thc liquid fuel to pass freely into the main feed-pi ie and thence direct to the supply-pipe. The

main feed-pipe and its branch form an im- .portant feature of my invention, as the supply of fuel will be constant, no matter in what position the implement may be held or` su ported..

nstead of connecting the main feed-pipe with the chamber in thc casing 3() l may dispense with said casing and its valve and arrango the said feed-pipe so that the flow of the fuel will bc direct to the supply-pipe, as In this instance the llow Y of the fuel to the supply-pipo is regulated by A. pipe.

a cone-valve 36, attached to the cnd of th(l supply-pipe in any well-known manner. The bottom of the chamber is conical lo form a seat for the valve 36, and a central aperture or port 37 places said chamber in communication with thel main food-pipe. I4" .led into the open cnd of tho chamber 27, which is screw-threaded, is a screw-thrcadcd packing;- gland 38, luiviugF a smooth bore through which projects the valved ond ol' thc supply- The end ol thesupply-pipc is provided With suitable ports oropcumgs 39 for the inflow ofthe liquid fuel. i Mounted rip;-

idly on the supply-pipe vis a collar 40, and

fitting over said collar is a cap or housing 4l internally screw-threaded to receive the externally-screW-threaded end of a connecting and operating; nut 42. r .he other end oi the nut 42 is internally screw-threaded. to receive the externally-screw-threaded end ol' the hub 26, and its outer periphery is provided with corrugations 43 to fucilitate the operation of the nut in moving tlv` supplypipe to and fro to adjust the valve to its sont. W hen the cap 41 and the nut 42 are screwed together, it will be'seen that the collar l0 is firmly confined therebetween, and by uuscrewing the nut more or less from thc end of the hub the valved supply-pipe may be moved from the seat at the bottom of the chamber 27 without disturbing the relative position of the cap and nut. The screwthreads on said nut being right and left hand, respectively, readily permit the accomplishniont of this operation. 'ily turning the nut in the opposite direction, or, in other words, screwing it up, the valvcd suppl^ \fpipe will be forced to its to cut oil the supply of fuel to said pipe, and consequently to the burner.

A further modilication of the leed-pipe is shown in Fig. 8, in which the main pipe is shown extended through the supply-pipe to the burner, and a suitable packing 44, preferably asbestos, is ticked around the extended portion oi said pipe to ker-,p the su ply-pipe cool. T he valve for controlling;r t ie llow olf the fuel to I[he supply-pipe is dispensed with, and in its stead the end'bf seid extended portion is contracted, as shown at 45, the supply of fuel to the burner ybeing controlled by said contracted cud and a needle-valve 4G of the burner 29.

rlfhe burner .29 is attached to outer end of the supply-pipe by :my suitable and wellknown means, pre erahly by a simple screwthreaded connection 47, as shown iu Fig. 2, consisting!` of a packing-ring 48 and a nul 49. Such n connection has been lound in practice lo prevent leakage.

The supply-pipe is loosely packed with usbcstos, as shown in Fig. 2, which serves the double purpose, of filtering und cooling agent.

In making lhe burner l prefer 'lo vast it practically solid and drill out the huid-pussage 50, excepting a part of the entrance ortion, which may bc cored, closing; the ciu s of the drill-holes by plugs 5l, us shown in Fig. 2, although'it may be constructed like the burner shown in the pat-outs granted to me August 2l, 1R33, No. 338,187, und September 4, i394, No. 525,494, respectively, where- IOO IOS

preferably by or hood is provided with suitable portion a slight distance beyond'lthe point I vide asuitable suppor The base of the burner is cut awayl ato @soldering tools or.points-such, for instance, y as ,the solderingfpoint 57iand the soldering- 58, the latter being speciallydaptedffor tf'slderin'g' telegraph andv other electric wires. '-Ti'esepoints or tools vnected to a screw-threaded collar or nut 59,

sides, as shown at a., to receive t e arms' or lugs b ofa nozzle 54, and the remaining portions 55 are screw-threaded to receive a shield or hood 56, to which mfy be attached interchangeably various kin s of are detachably conmeans of a bayonet joint or connection, and b y: the ycollar tothe shield or hood, as shown in 2 and 3. The shield openings for the escape of the gases `and for draft urposes. A Aconnection as above described provides for a ready and quick interchange oftools or points, as each tool or point is formed with a collar having oppositel disposed lugs 61 61, a. aptedto enter te behind the fianges the collar; or nut tightly j of` the vshield the tool or 'p oin't will be held Vfirmly in operative ositio dp form iii burner-nozzle and shield, the two combined in one integral part. The numeral ftindiof the combined nozortion is provided with oppositely-dis ose lugs 66 66, which are adapted to fit t e cut-away portions a of the/ burner, said lugs being formed with out ps 67 67 for a purpose to be hereina er described. The outer end of the nozzle portion projects within the shield (c) of juncture with the shiel The outer end 68 of the shield portion is screw-threaded, and a ,connecting collar or nut 69, similar to collarl 59, is employed to attach the various points or tools to said shield. The combined nozzle and shield is connected to the burner by a collar or nut 70, similar to collars 59 and 69, provided with recesses 7171, ada ted to receive the lips 67. The cou ling is e ected by slightly turning the com 'ined nozzle and shield to set the lipsy behind the shoulders 7 2 72 of the collar aid then lscrewing said collar tightly into p ace. l

In order to adapt my soldering implement for use in soldering th caps on cans, I proconsisting of a ase 73', a standard or arm 74, having 'a hollow head 75, and a spring-pressed operatingrod 75. To the upper end of the o erating'- rod is pivoted by a set-screw76 a-bifurcated head 77, to which is bolted a two-part bear- 78, in.-which the soldering implement is secured, as shown in Fig. 13 with the casin of the valve 46 resting in the bifurcation 0I the head 77 The lower end of the o eratin -rod is enlarged and flattened an provi ed with a camslot 79, in which operates an ovalsha ed cam 80, mounted eccentrically on a shait 81, vsuitably journaled in the standard 74. The shaft 81 is provided with a bandwheel 8 2, which is driven from any suitable source of power, The ends of the base are slotted, one being shown at 83, to provide for the attachment of a vertical crank-rod (not shown) to the operating-rod 75 if it should be desired to dis ense with the shaft and cams and operate tllie rod 75 by treadlepower.

In the o eration of soldering the caps o'n cans it is ogvious from the foregoing descri tion that the soldering implement vwill e brought intermittently down to the work, so that the operator both hands to manipulate the cans.

Having thus full described my invention, what I claim, and desire to secure by Letters Tatent, is-
